jaikiran pai commented on JBAS-8786:
------------------------------------

This _appears_ to be a VFS3 thing (r101688) in AbstractWarDeployer where it does a getExplodedWarUrl. Assigning this to Ales for now, to see if he has any inputs on how to fix this.

> while starting JBoss AS it unpacks all jar files, which are located in WEB-INF/lib folder of each my war file. It means that in tmp folder mostly I see folder with jar file, and folder with its content. E.g. jackrabbit-server.war contains library asm-3.1.jar, then in tmp folder I see the following folders with files:
> asm-3.1.jar-83dc35ead0d41d41/asm-3.1.jar
> asm-3.1.jar-2a48f1c13ec7f25d/contents/"unpacked asm-3.1.jar"
> actually when I repack jackrabbit-server.war to jackrabbit-server.ear which contains jackrabbit-server.war and moved all its libraries to jackrabbit-server.ear/lib then I still see two folders in tmp:
> asm-3.1.jar-215a36131ebb088e/asm-3.1.jar
> asm-3.1.jar-14695f157664f00/contents/
> but in this case last folder is empty. So it still creates two folders, but does not unpack my library. Also I use exploded deployment so the question is only about jar files, not unpacking ear/war.
> the problem is that it slows down application server booting (when I repack all my war files as ear and moved war libraries to ear/lib folder then I save 2+ minutes at JBoss 6 booting...). If it is done deliberately (so it improves some performance at runtime), then would be nice to have a configuration option, so during development I can save time to boot my local JBoss AS
